Application December 2, 1944, Serial No.1566, 3vil0 Y i claims.- 51.46-179) My inventionrelates to soundvproducing toys.. A n object of my invention is a 'toy that produces a whistling sound when jerked. f K

Other objects are a toy containing a voice,

whistle or any sound producing ldevice operated l by draught of air, to create this draught Aof air by themovement of a piston in aV cylindrical,` space of the toy, and to causethis movement by'jerkin'g the toy, thereby avoiding the use of a" gear or ofy machinery for driving the piston and operating the voice. y y

` Further objects are to provide a toy having two parts which move relatively to eachother by the inertia' of one of thesel parts when the other part is jerked, to create an air suction by this relative movement, and to operate a sound v'producing device byA this air suction. n v y j Still other objects are a toy of this kind which ha'shandy means adapted to jerkuthe toy or to move it quickly or adapted to move the toy reciprocatingly orto make the toy oscillate, and a toy of this kind containing resilient means damping or softening the impact of the piston at the end of a stroke, and resilient means causing the piston to reverse its moving direction and causing the piston to return to its original position when the jerking operation ceases.

Still further objects are to produce a toy of this kind in which the maximum simplicity of construction and operation is secured, and to attain a surprising eiect by this very simplicity.

Still further objects and advantages will appear from the following description of exemplifying embodiments of the invention, from the appended claims, and from the drawing in which:

-Fig. 1 shows a longitudinal central cross-section through an illustrative embodiment.

Fig. 2 shows a cross-section through the same embodiment, said cross-section being taken along the line 2 2 in Fig. l.

Fig. 3 shows a longitudinal side elevation of another illustrative embodiment.

Fig. 4 shows the latter embodiment seen from the upper side in Fig. 3.

Most of the parts used in thev embodiment shown in Figs. 1 and 2 are identical to parts used in the embodiment shown in'Figs. 3 and 4. With respect to these identical parts, Figs. l and 2 may be regarded as complements of Figs. 3 and 4, and vice versa.

Referring to the drawing, numeral I indicates a f casing or outer body which may be cylindrical and may comprise a main body and a cover 2. An inner body or piston 3 is slidably inserted in the body I and has a hole passing through the body 3 in the sliding direction. This hole' is filled with asound producing device which may be constituted by a capsule or hollow member 4 or may have any other suitable-structure operated by air passing from one side of the piston 3 to the 'other'.

The capsuleV 4 contains a hollow space connected by a hole to'one sideand by va'hole Iil to thek other side of the'space in which the piston slides wherebyymovement of the piston will drivev or suck air through Athe capsule and, thereby, produce a whistling noise.v The capsule may becomposed of two parts shaped like cylindrical cups having bottoms containing the holes 5 yand 6 vrespectivelyv and having side walls tightly'contacting each other. f Preferably, the cover 2 has a number of holes l, and similar holes 8 may be provided in the wall of the casing I and'may be positioned pear the edge of the cover 2. This edge forms va stop for the movement of the piston 3 in one direction'. 'f In the other direction, a similar stop may b e formed by a, cylindrical ring'9 inserted in the casing I. The air contained in the inner space of the ring 9 together with the air in the recess [Il of the pistonV 3 forms a cushion which is resiliently compressed or dilated when the piston reciprocates and contributes to the eiiiciency of the air current operating the whistle 4 while, at same time, softening the stroke of the piston against the ring 9. This stroke may be further softened by a resilient cover of the stoppingl edge of the ring 9, for example by a cord II laid over the stopping edge and having ends wedged between the walls of the ring and of the casing I.

The parts which have been described so far may be used identically in both illustrated embodiments. 'I'he two embodiments differ merely in the means to create inert forces causing the piston andthe casing to move relatively to each other;

In the embodiment shown in Figs. l and 2, the inner body 3 is jerked, and the outer body I lags due to its inertia. The jerking pull may be transmitted to the piston 3 by acord or string I2 passing from the open i'nto the casing I through a hole I3 and having an inner end amxed to the piston in any suitable manner. For example, a wire I 4 may have ends wedged into the piston and may form a bridge in the center of which the string I2 is attached by means of a knot I5. The

hole I3 may be surrounded by a guide ring I 6 Y riveted to the cover 2.

A 'spring II may be wound around the inner part of the string I2 and maybe compressed by the impact of the moving piston 3. This spring tends to reverse the moving direction of the pistion while, in the rst described embodiment, the casing is suspended and will make leaping movement in a substantial vertical direction.

In both embodiments, the piston 3 divides the inner space of the casing into two parts, partitioning off a partial space surrounded by an uninterrupted or solid part of theA casings wall and having no other outlet than the hole E whereby the air confined in this part is forced vehemently through the whistle 4 when the piston 3 moves relatively to the casing. Preferably, that part of the casings wall which borders or surrounds the space positioned at the other side of the piston has perforations, forexample the holes 8, permitting air and sounds to pass into the open.

The bodies I and 3 are free to fly between the end stops under the influence of inert and resilient forces, these bodies being free from any other kinematic connection thanv thecontact of their sliding surfaces, no gear or machinery being used to enforce their relatively sliding movement.

I desire it understood that my invention is not confined to the particular embodiments shown. and described, the same being merely illustrative, and that the invention may be carried out in other Ways without departing from` the spirit of my invention as it isY obvious that the embodiments shown 'and described are only a few of the many that may be employed to 'attain the objects of my invention.

Having described the nature of my inventionand how it operates, what I claim and desire to secure by Letters Patent is:

1. A sounding toy comprising a hollow body member, a piston member slidably mounted within the hollow body member and movable therein from end to end, an air duct extending through said piston member from one face thereof to the other for air iiow therethrough as the piston moves within the hollow body member, spring means urgingsaid pistonmember in one direction, manual means attached to oneof said members for quickly moving one of said members relative to the other and against the force of said spring means. and an air operated sounding device operable by air ow in either direction therethrough mounted on the piston member within the air stream flowing through said duct when said members are relatively moved.

2. Asounding toy of the character described in claim 1 wherein the manual means comprises ,a handle connected to said `hollow body member with the axisv of the handle generally transverse to thevpath of movement `of the piston Within said hollow body member.

3. A sounding toy of the character described in claim 1 wherein said manual means comprises a flexible strand connected to said piston member and wherein said spring means urges the piston member into -the lower end of said movable member.

4. A sounding toy of the character described in yclaim 1 wherein said spring means urges said piston to one end of said hollow body member, and wherein saidmanual vmeans is a exible strand attached tosaid piston member and operable to move the piston member against the force of said spring away from said one end of the hollow body member, and guide means carried by the opposite end of said hollow body member and through which said flexible strand passes.
